  • Resolving fine spectral features in lattice vibrational modes using femtosecond coherent spectroscopy

    摘要： We show resolution of fine spectral features within several Raman active vibrational modes in potassium titanyl phosphate (KTP) crystal. Measurements are performed using a femtosecond time-domain coherent anti-Stokes Raman scattering spectroscopy technique that is capable of delivering equivalent spectral resolution of 0.1 cm?1. The Raman spectra retrieved from our measurements show several spectral components corresponding to vibrations of different symmetry with distinctly different damping rates. In particular, linewidths for unassigned optical phonon mode triplet centered at around 820 cm?1 are found to be 7.5±0.2 cm?1, 9.1±0.3 cm?1, and 11.2±0.3 cm?1. Results of our experiments will ultimately help to design an all-solid-state source for sub-optical-wavelength waveform generation that is based on stimulated Raman scattering.

  • Treatment of Vocal Fold Polyps with In-Office Potassium Titanyl Phosphate (KTP) Laser Ablation in Professional Singers

    摘要： Vocal fold polyp (VFP) is an exophytic gelatinous lesion with an atrophic epithelium. After behavioral and conservative management, phonomicrosurgery is the treatment of choice for VFPs with excellent outcomes in terms of lesion resolution and postoperative vocal function. Office-based potassium titanyl phosphate (KTP) laser ablation is a new treatment modality for VFPs but its efficacy for professional singers has yet to be validated. Reported is a consecutive series of six professional singers (with seven episodes of VFP) who, based on patient and provider preference, underwent in-office KTP laser ablation of VFP. Two polyps required two ablation procedures; otherwise, a single treatment was successful in resolution of VFP at a mean resolution time of 44 days. Singing voice handicap index 10 improved from a mean of 30.8 (range 4?40) to 6.0 (range 0?22). All patients resumed their professional singing careers without vocal limitations. Posttreatment videos were reviewed by three blinded fellowship trained laryngologists, who were not able to accurately predict the laterality of the polyp (52% correct, p = 0.99).

  • Successful treatment of multinucleate cell angiohistiocytoma in an adult male patient with potassium-titanyl-phosphate laser in combination with intralesional corticosteroids

    摘要： Multinucleate cell angiohistiocytoma (MCAH) is a rare, benign, idiopathic disease characterized by strong female predominance and predilection for the extremities and face. Most often asymptomatic, MCAH follows an indolent, yet progressive course, with spontaneous remission being uncommon. Many aspects of this vascular and fibrohistiocytic proliferation are controversial, including pathogenesis and treatment recommendations. We present a case of MCAH in a male patient successfully treated with potassium-titanyl-phosphate (KTP) laser.
